Not a critical problem. But module_init() are preferred for modules.
This was intentional. When compiled as a module, subsys_initcall becomes
module_init(). When compiled in-kernel, this code is

There are no dependencies. fsldma registers with the DMA engine,

Re-read my explanation, please. Technically, it

Modify the Freescale Elo / Elo Plus DMA driver so that it can be compiled as
a module.
The primary change is to stop treating the DMA controller as a bus, and the
DMA channels as devices on the bus. This is because the Open Firmware (OF)
kernel code does not allow busses to be removed, so
